Things like this make me wish there was a sort of public version of Tailscale where everyone got a routable IP address to everyone else no matter what kind of firewall they were behind. Like the old days of the internet, I guess.
We might one day have it natively with ipv6 adoption increasing.
You share some "semi-public" host with all of your friends...
And then you're not necessarily chatting with famous people, but you can have a near-and-dear-social network of people you actually know...
